4 Safety DALI RC BASIC SO Safety General instructions Safety instructions The control unit must only be installed and put into operation by a qualified electrician. The applicable safety regulations and accident prevention regulations must be observed. WARNING! Exposed, live cables. Danger of electric shock! Only work on the control unit when it is de-energised. CAUTION! Destruction of the control unit and other devices through incorrect mounting! Adhere to the connection diagram. Supply the control unit via an AC power supply only. Do not route sensor and pushbutton lines together with power supply lines in the same cable. When routing DALI and power supply lines together, make sure that they are sufficiently insulated. Do not connect additional DALI supplies or DALI control units in the system to avoid exceeding the max. permissible total current of 250 ma. The DALI interface should be treated as a mains supply. Only connect DALI components to the DALI interface. Do not connect the mains supply to the DALI interface. Do not combine the control unit with a mains-voltage operated pushbutton controller. Always connect pushbuttons to a floating contact. Do not exceed the maximum total line lengths and the corresponding line crosssections. Do not exceed the maximum number of connectable components. 4 VII 2009

5 DALI RC BASIC SO Description Description Purpose and application Function Design The DALI RC BASIC SO control unit can be used for both scene-based open-loop control and daylight/presence-dependent closed-loop control. The control unit can control up to 64 DALI units (ECG or converters). The functions are operated on standard pushbuttons. Light control The control unit enables the variable formation of 4 luminaire groups whose individual brightness settings can be used to set up and store 4 scenes (lighting situations in a room). Brightness control In scene 1, the brightness of up to 3 luminaire groups can be controlled by connecting light sensors (DALI LS BASIC): The sensors measure the brightness in the area requiring control and keep it to an adjustable set value by introducing artificial light according to the amount of daylight available. Motion detection In addition, by connecting combined light and motion sensors (DALI LS/PD BASIC), all luminaire groups can be switched on and off depending on the presence of persons. The control unit is made up of the following components: Connection terminals (A) Reset button (B) Adjusting screw for switch-off delay time (C) LED display (D) Housing (E) A B A C D A E A VII

6 Installation DALI RC BASIC SO Installation Installation notes A maximum of 64 DALI units can be connected. A maximum of 6 sensors can be connected, either all on a single LS input or distributed over the inputs LS 1 to LS 3, depending on the application. If multiple light sensors are connected in parallel to an LS input, the light value is averaged. The control unit contains the power supply for the DALI interfaces and the supply voltage for the sensors. If the DALI lines are overloaded for a long period or short-circuited, the DALI interface switches to high impedance until the fault is eliminated. The green On LED goes out and the red Fault LED lights up. The fault contact is not closed in this case. The motion sensors are automatically detected when the mains voltage of the control unit is connected, but their removal is only detected after power is disconnected. The light sensors are always detected. All motion sensors connected to the PD input act in parallel (detection area extension). After the mains supply is connected, motion detection is suppressed for 1 minute. Standard pushbuttons can be used for operation (make contacts with basic insulation). To make full use of the functionality, a 5-fold pushbutton field is required (e.g. DALI WCU 5 BASIC W). The pushbuttons can be connected in parallel to be able to operate the lighting system from different locations. An optional signal lamp may be connected. Other connections are possible using the floating contact. By using DALI converters, it is also possible to transfer the functions of the control unit to existing V / V systems. 6 VII 2009

9 DALI RC BASIC SO Installation Brightness control of luminaire group 1 and motion detection (with two sensors) The sensors are connected in parallel to LS1 and are thus assigned to luminaire group 1 (the light measurement values are averaged). The sensors are connected in parallel to the PD (more sensitive motion detection or enlargement of detection area). à Luminaire group 1: brightness control with motion detection in lighting scene 1 à Luminaire groups 2 to 4: light control with motion detection (calling up of lighting scene 1) Mains voltage 230V~ 50/60Hz Signal lamp (optional) To the DALI operating devices Pushbuttons VII

10 Installation DALI RC BASIC SO Brightness control of luminaire groups 1, 2 and 3 and expanded motion detection (with three sensors) The sensors are connected to inputs LS1 to LS3. The brightness control is thus permanently assigned to each of the luminaire groups 1 to 3. The sensors are connected in parallel to the PD (more sensitive motion detection or enlargement of detection area). à Luminaire group 1 to 3: brightness control with motion detection in scene 1 lighting à Luminaire group 4: light control with motion detection (calling up of lighting scene 1) Mains voltage 230V~ 50/60Hz Signal lamp (optional) To the DALI operating devices Pushbuttons 10 VII 2009

12 Installation DALI RC BASIC SO System and fault messages The system and fault messages are displayed using the LED located in the device or optionally via a signal lamp connected to the fault contact, or are forwarded to a higher level system. LED State Meaning Green "On" LED Yellow "Send" LED Red "Fault" LED Flashes On On Flashes On Lock mode is active. Control unit is operational. Communication on DALI interface. No DALI units are connected, DALI lines are disrupted or short-circuited. The fault contact switches at the same rate. The lamp of an active DALI ECG is faulty. The fault contact is closed. Behaviour after a power failure If the power supply to the control unit fails, connected DALI units that are still supplied with power are switched to maximum brightness (see also the corresponding manufacturer information). When power returns, the control unit automatically restores the lighting system to its status prior to the failure. 12 VII 2009

14 Operation DALI RC BASIC SO Performing a reset In the basic setting, all luminaires are assigned to luminaire group 1 and scenes 1 to 4 are predefined. Note: In the following cases, the control unit automatically resets the system when the mains voltage is applied: When the system is being installed for the first time. If a luminaire has not yet been assigned to a group. Proceed as follows: Step Task Result 1 Switch off the mains supply of the control unit and wait for the "On" LED to go out. 2 Switch the mains supply back on while pressing the reset button. 3 When the red "Fault" LED goes out, release the reset button. All group assignments and scene settings are cleared. Defining the luminaire groups Note: Light sensor inputs LS1 to LS3 are permanently assigned in the control unit to luminaire groups 1 to 3. When defining the luminaire groups, ensure that they are arranged according to the light sensors (luminaire group 1 for the light sensors on LS1, etc.). A light sensor cannot be connected to luminaire group 4 and brightness control is not possible. Proceed as follows: Step Task Result 1 If necessary, unlock the luminaire group assignment function; see "Locking luminaire group assignment and scene storage". 2 Press the central button, button 1 and button 2 simultaneously and hold for approx. 5 s. All luminaires flash. 14 VII 2009

15 DALI RC BASIC SO Operation Step Task Result 3 Within the next 10 s, press the central button gain and hold for approx. 5 s. 4 Press one of the pushbuttons 1 to 4, corresponding to the required group. Note: Each DALI unit can only be assigned to one group. The brightness of all luminaires is reduced to a minimum. The control unit searches for existing DALI units. When a unit is identified, its lamp begins to flash. Note: The search for DALI units can take several seconds. The order in which the units are found is random. The flashing luminaire is assigned to the corresponding luminaire group 1 to 4. The brightness of the luminaires that already belong to the selected luminaire group is set to the maximum value, while the luminaire of the unit being assigned continues to flash. The luminaires of all other units remain at minimum brightness. 5 If necessary, change the assignment by pressing another button 1 to 4. 6 Press the central button. The assignment to a luminaire group for the current unit is stored. All luminaires are set to minimum brightness again. The control unit automatically searches for the next DALI unit. 7 Repeat steps 3 to 5 until all luminaires are assigned. After the last unit is assigned, all luminaires flash 1x. The group assignment mode is ended automatically. Note: Changes in the luminaire group assignment are not yet included in the existing lighting scenes. Therefore, the lighting scenes need to be adjusted and stored after the luminaire group assignment is changed. 8 If necessary, test the luminaire group assignment; see "Testing the luminaire group assignment".
